I have an idea for a mod but since im not a modder or have ever made one its best left to the professionals.
My idea is for 2 New Lightsaber forms to be added that werent in TSL yet are in the Star wars Universe- Form V Variant Djem So and Jar Kai for dual wielders.

My idea for them is below

Djem So

Vs Lightsaber Wielders
Vs One on one combat
Unstoppable in one on one combat (feat?)/ Chance the opponent can be knocked down with attacks
Stength with Lightsaber increased by 1 / The Force enhances your strength for a time

Must master Shien 1st to learn Djem So
Shien changed to give all defense vs blaster feats
Shien more proficient at returning blaster bolts
Form III (soresu) amended to give the same with defence feats to blasters
